Who it’s for
Friends, partners, housemates, and trip crews who split costs and want clear balances without giving a product custody of their money.
Early access
SettleDrop
SettleDrop is Core Trail Labs’ early-access product for shared expenses. It clarifies who owes whom across trips, housemates, and group events — while deliberately never holding or moving money. Settlement stays between people; SettleDrop keeps the balances honest.
Shared expenses without holding money
The problem
Shared spending usually lives in chat math, screenshots, and half-updated spreadsheets. Someone becomes the unofficial banker. Payment apps move money but do not keep a fair ongoing picture of who owes whom across a whole trip or household.
How SettleDrop approaches it
SettleDrop focuses on transparent balances and settlement intent. It is not a wallet, not a payment rail, and not a place for funds to sit. The product job is clarity: track expenses fairly, show what is owed, and leave the actual transfer to whatever channel people already trust.

Who it’s for
Groups that share costs, not custody
SettleDrop is for people who already trust each other enough to settle directly — they just need a clearer ledger than a chat thread.
- Trip crews splitting hotels, meals, and transport.
- Housemates tracking recurring shared costs.
- Friends running events where many people pay in turns.
Product boundary
Clarity without holding funds
The hard line is intentional: SettleDrop does not hold or move money. That keeps the product focused on fair tracking and reduces the trust surface that comes with custody.
- Balances and settlement intent stay visible.
- Actual payments happen outside SettleDrop.
- No wallet balance to reconcile against real life later.
